Plei-Tech custom molded polyurethanes are frequently used in demanding applications where shock absorption, vibration dampening and noise reduction are required. Common urethanes that do not exhibit excellent dynamic performance, low compression set, and high cut and tear resistance will quickly fail in these vibration damping applications.
Pleiger Plastics can design and test shock absorbing bumpers to develop stress and strain curves
required for bump stops, damping bumpers and bumper systems.
Shock absorbing applications are both common and highly variable, since they can include prosthetics, coal car draft gears and pump check valve balls. Equipment bumpers can be designed for shock absorption on loads from 1 to 200,000 lbs.
The Jobel impact bar is a specially designed impact system for use on conveyor belts to increase belt life at transition points.
PT-15 Foam is a material used for bumpers where low load and high frequency occurs. This molded foam material can be compressed as much as 70% with little permanent compression set.
